[0020] Referring to Figures 1 to 6The embodiment 1 is a steady flow and noise reduction device of a water inlet valve, the water inlet valve is provided with a water inlet pipe 1, a rectifier 2 of the steady flow and noise reduction device is limitedly arranged in the water inlet pipe, the rectifier is outwardly and downwardly buckled with a filter 3, the outer periphery of the rectifier is provided with eight limiting ribs 6, the gap between every two limiting ribs forms a water inlet channel 7 extending along the water inlet direction of the water inlet pipe with the inner wall of the water inlet pipe; an O-shaped sealing ring 4 and a deformable O-shaped ring 5 are sequentially sleeved downwardly at the limiting end of the rectifier, the limiting part of the water inlet pipe is sealed by the O-shaped sealing ring, the deformable O-shaped ring is extruded and deformed by water when the water supply pressure is high, the extruded and deformed part of the deformable O-shaped ring extends to the water inlet channel, so that the water area of the water inlet channel is reduced to form a steady flow structure; the water inlet channel is provided with an inner convex rib 8, the extruded and deformed part of the deformable O-shaped ring is limited by the inner convex rib.

[0021] With reference to Figures 7 to 10 The difference between the embodiment 2 and the embodiment 1 is that the rectifier and the filter are inwardly buckled.

[0022] The utility model discloses, when water inlet, the water of water supply pipe enters along the water inlet direction through the filter, because the deformable O-shaped ring is arranged at the top of the filter, so that the water inlet valve is at low water pressure, the water inlet pressure is small, the extrusion of the O-shaped ring is small and basically has no deformation, and the flow is not lost, when the water inlet pressure is high, the water inlet pressure is large, and the water flow extrudes the inside of the deformable O-shaped ring to the water inlet channel, so that the water area of the water inlet channel is reduced, thereby controlling the flow of high pressure, achieving the purpose of reducing the flow, when the water pressure reaches a certain degree, the sealing ring is deformed close to the limit, the water area tends to be fixed, basically achieving the stable flow, thereby achieving the purpose of controlling the flow of high and low pressure basically stable, so that the steady flow achieves the effect of reducing the noise.
